  • *The Swedish inpatient register does not distinguish between type 1 and type 2 diabetes mellitus.

  • †We did not include sepsis caused after abortion, transfusion, surgery, immunization, or while giving birth. Neither did we include sepsis that was specified as as being caused by actinomycosis, anthrax, candidiasis, extraintestinal yersiniosis, gonococci, listeriosis, meiloidosis, Yersinia pestis or tularaemia.

  • ‡In ICD-8 there are only available data on E coli.

  • §In older classifications “Staphylococci” were not divided into “Staphylococcus Aureus” and “other Staphylococci”. For that reason we have looked at any Staphylococcal sepsis throughout the study period.
